Trypsin (EC3.4.21.4) is part of the serine protease family. Trypsin cleaves lysine and arginine at the C-terminal side of the peptide. The hydrolysis rate is slower if an acidic residue is on either sides of the cleavage site and no cleavage occurs if a proline residue is on the carboxyl side of the cleavage site....

Primers are provided as a 40 µl solution containing both primers at a final concentration of 50 µM in 10 mM Tris-HCl (pH 7.5), 0.1 mM EDTA. Dilute with water as needed prior to use. This amount is sufficient for 1000 x 20µl PCR reactions assuming a final primer concentration of 0.1 µM. Add cDNA template....
